Hi there,<br />
<br />
I'm currently using Talend Open studio Data Integration to managing the importation of several Excel spreadsheets. However, what I've found is that some of these spreadsheets can change slightly: field names change, what was once single sheets are split into multiple sheets, column orders change.<br />
<br />
What I want to know is has anyone encountered these problems in ETL design and is it even possible to overcome these issues and if so what technologies were used? Is it even possible in principle to account for changing Excel formats when importing data into a database?<br />
<br />
Thanks,<br />

Hi there,

I'm currently using Talend Open studio Data Integration to managing the importation of several Excel spreadsheets. However, what I've found is that some of these spreadsheets can change slightly: field names change, what was once single sheets are split into multiple sheets, column orders change.

What I want to know is has anyone encountered these problems in ETL design and is it even possible to overcome these issues and if so what technologies were used? Is it even possible in principle to account for changing Excel formats when importing data into a database?

Thanks,

Manage changing Excel formats during ETL - in principle

Microsoft Excel topics include formulas, formatting, VBA macros and user-defined functions, and everything else related to the spreadsheet user interface, including error messages.

Microsoft Excel

A spreadsheet is an interactive computer application program for organization, analysis and storage of data in tabular form. Spreadsheets developed as computerized simulations of paper accounting worksheets. The program operates on data represented as cells of an array, organized in rows and columns. Each cell of the array may contain either numeric or text data, or the results of formulas that automatically calculate and display a value based on the contents of other cells.

Spreadsheets

Databases are organized collections of data, most commonly accessed through management systems including schemas, tables, queries and processes that allow users to enter and manipulate the information or utilize it in other fashions, such as with web applications or for reporting purposes.

Databases

Visual Basic for Applications (VBA) enables building user-defined functions (UDFs), automating processes and accessing Windows API and other low-level functionality through dynamic-link libraries (DLLs). VBA is closely related to Visual Basic and uses the Visual Basic Runtime Library, but it can normally only run code within a host application rather than as a standalone program. It can, however, be used to control one application from another via OLE Automation. VBA is built into most Microsoft Office applications.
